Bitcoin's protocol cuts the block subsidy (the halving) roughly every 210,000 blocks — historically about every four years. That supply-epoch rhythm is the usual anchor when people talk about a “4-year cycle.” Treat it as educational framing and historical observation, not a promise that the next epoch will rhyme on cue.
Historically the market has often rhymed in roughly four-year cycles: about ~3 years up and ~1 year down as an approximate framing only. Lengths, depths, and calendar dates differ across cycles — use “historically / often / approximately,” not certainty.
An interesting open question: nobody has a settled answer whether the rhythm is driven by the halving itself, liquidity, the business cycle, or something else. The “why” is still debated; the diagram below is observation and framing for study.

~3-year bull
~ early / mid expansion
Historically, risk-on stretches after major bottoms have often lasted on the order of a few years — roughly framed as about ~3 years of expansion before a larger reset. The earlier part of that stretch is the quieter rebuild / expansion zone on the schematic. Treat the length as an approximate study aid, not a stopwatch.
Halving epoch
~210,000 blocks · mid-cycle zone
The Bitcoin protocol cuts the block subsidy roughly every 210,000 blocks (historically about every four years). That supply-epoch event is the usual anchor of “4-year cycle” talk — shown as a blue mid-ascent zone on the schematic, an educational reference point, not a trade signal or a promise that price must rhyme with the next cut.
Late bull
post-halving → peak
After the halving-epoch zone and before the red drawdown, observers often talk about a late-bull stretch where price action tends to get more crowded, leveraged, and unpredictable. That label is descriptive vocabulary on the orange band only — not a timing model, precise split date, or promise of how wild any given cycle gets.
~1-year bear
~1 year · drawdown / reset
Historically the market has often spent on the order of ~365 days in a broader drawdown / reset after a major cycle high — a rough framing only. Depth, shape, and calendar length vary by cycle; this is observation language for study, not a forecast of the next decline.
